Hi Hugh,
If you want to run only one instance of your standalone at a time, you
need to include a relaunch handler in your stack script. Assuming that
you want the existing instance to come to the foreground when the
second instance is launched and that you want the second instance to
quit immediately, all you need is to catch the message and not pass it:
on relaunch
return empty -- just for clarity, if you like
end relaunch
If you return "background", the second instance is terminated, but the
first instance won't be activated. If you pass the message, the second
instance will run.

Goal:
Using shell()to determine if my Rev app is among the line of all
running
processes. If so, then user has started a second instance and I want
to
quit.
Task 1: Get a list of all running processes and IDs.
Task 2: Get the process name and ID of my Rev app.
With me so far? Okay...
I should be able to get a list of all running process using "ps -e"
(according to http://www.ss64.com/bash/ps.html).
So I try this in the message box, hoping to see some sort of a list:
answer shell("ps -e")
What I get instead is 'ps is not recognised as an internal or external
command, operable program or batch file.'
Same result using shell("top") and shell("list-processes").
So what stupidity am I doing, please (apart from naively expecting the
syntax to work)? And how do I get the process name & ID of the app?
